Most of the rioters are Bernie supporters in Portland and Seattle, why Joe is letting Bernie dictate his stances on the issues now. If they try to dump Biden now, they'd only be satisfied with a Bernie nomination.
I think there's a decent chance he might not even be up against Biden. Joe is getting worse by the day, the media is protecting him as much as they can but there's no hiding it now.
I usually am very accurate with the presidential elections but only about the day before the election - I thought Hillary would win until the last minute, I knew Obama was going to win both times, the same with GWB against Kerry but until two days before the election, I thought Algore would take it.
It seems historically, riots favor the GOP - Reagan over Brown, Nixon over Humphrey. But this is not a typical election year, polls are off when you consider you don't want to voice your opinions in a toxic speech environment. Trump's to lose for now.
